Darwin’s readings took him to a predictive theory of how species might change with time: what later thinkers have called microevolution.

For your thread:
According to Chapter 13 section 13.1, define microevolution and macroevolution.
The Galapagos islands have a great diversity of landscapes – from lush vegetation to nearly barren lava fields yet the Galapagos Finches survive on each island. How can this be explained?
